We are Riddhi Siddhi Impex, a Mumbai-based Incoloy 825 Strips manufacturer and supplier, established in 2002. We slit nickel-iron-chromium-molybdenum-copper Alloy 825 strip to ASTM B424 / ASME SB-424 in thicknesses from 0.03 mm to 5 mm. Our ISO 9001, 14001, and 45001-certified facility carries ready stock, with a monthly supply capacity of 400 to 500 tonnes, and issues EN 10204 Type 3.1 mill test certificates as standard, with Type 3.2 on request.
We provide ASTM B424 Incoloy 825 slitting coil in the annealed condition, in thicknesses from 0.03 mm to 5 mm and precision-slit widths from 3 mm to 2000 mm, with a choice of surface finishes and edges.

Alloy 825's corrosion resistance comes from copper and molybdenum. In UNS N08825 strip, 1.5 to 3.0% copper and 2.5 to 3.5% molybdenum resist reducing acids like sulphuric acid, while 19.5 to 23.5% chromium manages oxidising conditions. The nominal composition of UNS N08825 to ASTM B424 is shown below.
| Element | Composition (%) |
|---|---|
| Nickel (Ni) | 38.0 to 46.0 |
| Chromium (Cr) | 19.5 to 23.5 |
| Iron (Fe) | Balance (22.0 minimum) |
| Molybdenum (Mo) | 2.5 to 3.5 |
| Copper (Cu) | 1.5 to 3.0 |
| Titanium (Ti) | 0.6 to 1.2 |
| Carbon (C) | 0.05 max |
| Manganese (Mn) | 1.0 max |
| Silicon (Si) | 0.5 max |
| Sulphur (S) | 0.03 max |
| Aluminium (Al) | 0.2 max |
Annealed Alloy 825 strip carries a minimum tensile strength of 586 MPa with 30% minimum elongation, so it forms and draws readily. The values below are the annealed minimums for strip; yield and elongation vary with thickness and product form, so the applicable minimums should be confirmed against the mill test certificate for the ordered gauge.

These are the major applications for the 825 nickel alloy strips we slit. Buyers select the grade for its resistance to sulphuric acid, chloride pitting, and stress corrosion cracking.
Chemical plants use Alloy 825 strips for gaskets, sealing parts, and equipment linings carrying sulphuric and phosphoric acid. The copper resists reducing acids that attack stainless steel, and titanium guards the welded joints.
Oil and gas fabricators specify Incoloy 825 strips for sour service hardware exposed to hydrogen sulphide and chlorides. Slit strip is used for sealing components and corrosion-resistant fabricated parts.
Heat exchanger builders fit Alloy 825 strips into baffles, sealing strips, and expansion joints where acid condensate corrodes lesser metals. The grade resists pitting and crevice attack, and ASME SB-424 compliance suits pressure equipment.
Pollution control makers apply 825 nickel alloy strips in flue gas desulphurisation systems and scrubber internals that handle acidic condensates. The chromium and molybdenum additions help the alloy resist corrosion and chloride attack in these environments, and custom-slit widths form linings that fit each unit.
